The Seward Highway remains closed between Anchorage and Girdwood due to whiteout conditions from blowing snow, snowdrifts along the roadway and two avalanches this morning in the McHugh Creek area, a spokesman for the state transportation department said.

Some avalanche debris reached the northbound lane and highway crews are working in the area, said Rick Feller, a spokesman for the Department of Transportation and Public Facilities. The department and Alaska State Troopers have closed the highway between Potter Marsh and Girdwood, he said.

"It's zero visibility and extremely difficult driving conditions," Feller said.

Teams were looking closely at the snowpack elsewhere to see if explosives would be needed to clear other potential avalanche hazards, Feller said.
